    🤖 Gemini’s Gmail summaries were just caught parroting phishing scams. A security researcher embedded hidden prompts in email text (w/ white font, zero size) to make Gemini falsely claim the user's Gmail password was compromised and suggest calling a fake Google number. It's patched now, but the bigger issue remains: AI tools that interpret or summarize content can be manipulated just like humans. Attackers know this and will keep probing for prompt injection weaknesses.

    TL;DR
    ⚠️ Invisible prompts misled Gemini
    📩 AI summaries spoofed Gmail alerts
    🔍 Prompt injection worked cleanly
    🔐 Google patched, but risk remains
